BUILDER-MOTION.

Application led November 11, 1918.

To aZZ whom t 'may concern.'

Be it known that l, JESSE Jnrrnns, a citizen of the United States, and a resident of Uxbridge, in the county of 1Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Builder-Motions, of which the iol lowing is a specification.

My invention relate to builder motions for spinning and winding machines.

The object of the invention is to provide simple and effective means for positioning the yarn traverse rod prior to the commencement of the oper ation of winding the yarn upon the bobbins. In winding machines, as usually constructed, the yarn builder mechanism is located in the lower part ot the machine in close proximity to the floor. The proper-'starting position of the yarn traverse Vrod is obtained by the operative by means of a bell crank wrench transmitting a rotary motion to the builder shaft. The act of performing this operation is somewhat tedious to the operative owing to the stooping position that. has to be taken to accomplish the purpose. By means ot my invention this operation is accomplished by the operative while in a standing position and he is thus free to exert the necessary force without the tiresome effects.

`With the above mentioned object in view, the invent-ion consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the cla-im here to appended; it Ybeing understood that Vvarious changes in form, proportion, size and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrilicingl any of the advantages of the invention.

To more fully comprehend the invention, reference should .be had to the accompanying drawings, wherein- Figure 1 is a fragmentary end view showing my invention applied to ay quill winding machine t Fig. 2 is a side view of the same.

Fig. 3 is a fragmentary side view oit my improved builder motion lever.

Fig. 4 is a top plan sectional view of builder motion on line A B of Fig. 2 showing the manner ot hanging the builder motion lever to the frame of the machine.

Specification of Letters Patent.

Serial No. 262,100.

Fig. 5 is an end view of the builder motion take-up device.

Fig. 6 is Aan end view oi the locking device or the winding-down7 shaft.

Fig. 7 is atop plan view oi Fig. 6.

Referring more particularly to the several views of the drawings, wherein like characters oit reference designate corresponding parts, 1 indicates the end leg of a winding machine, 2 the connecting bar between the legs (but one of the legs being shown), 3 the bolster rail for holding a plurality of spindle holsters e, 5 the bobbins on the spindles 6, 7 the traverse rod to which a yarn guide wire 8 is fastened for each bobbin. The traverse rod rises and falls a pre determined amount depending on the length and kind of bobbin desired to be filled. Motion is communicated to the traverse rod through the push rod 9 actuated by the bell crank lever 10 the upper arm of which is connected by a chain 11 to the builder motion lever 12 fulcrumed on a stud fastened to the end leg 1. A vibratory motion is im-V parted to the lever 12 by the cam 14 acting on the follower roll 15 fastened to the lever 12.

The chain 11 is fastened to the periphery oit the ianged pulley 16 and is wound thereon by a rotary motion imparted to the pulley by means olf the worm gear 17 actuated by the worm 18 on the builder shaft 19. On the outer end of the shaft 19 is fixed a ratchet gear 20. A pawl 21, Fig. 5, acting with the teeth of the ratchet gear, is pivoted to the carrying lever 22 which is in a swingrelation with the hub of the ratchet gear. 0n the outer end of the pawl carrying lever 22 is a lug 23 provided with a hole in a fsliding relation with the take-up rod 24, fixed to a stationary part of the machine. The movement ot the pawl with relation to the ratchet gear is controlled by two abutting collars 25, adjustably mounted on the takeup rod 24. one above the lug 23 and the other below. The pa-wl is maintained in contact with the teeth ot the ratchet `gear by the compression or the spring 26 acting between the carrier arm 22 and theftal 27 of the pawl. As the builder motion lever 12 has a positive vibratory motion imparted to it by the cam 14;, it is evident that at each upward movement the lug 23 will be carried against the upper abutment collar 25 thus causing traverse rod which he does by means of a bell crank wrench acting on the end of the builder shaft. The position that he has to take in doingthis is very awkward and uncomfortable and where it has to be done many times during the days routine, becomes very tiresome to him.

rlhe foregoing construction and descrip tion is characteristic. of builder motions of winding machines as made at the present time.

In my improved construction the builder lever 12, Fig. 4, is provided with an enlarged hub 28V loosely mounted on the hollow stud 29 which is securely fastened to the frame 1 by the collar 30 andnut 3l. The hollow stud forms a bearing` for a short auX- iliary shaft 32 on the outer end of which is fixed the bevel gear 33 and on the inner end a skew gear 34 is fastened. rlhis gear meshes with gear 35 fixed to the builder shaft 19.V The bevel gear 33 meshes with bevel gear 3bV fixed to the wind-down"7 shaft 37 held in bearings 38 and 39 fixed to the frame of the machine. At the upper end of the shaft 37 a handle is xed by means of which the operative can impart a rotary motion to the flanged wheel 16 through the shaft 37, bevel gears 36 and 33, shaftl, skew gears 34 and 35, builder shaft 19, worm 18 and worm gear 17.

ln winding-down the traverse it is nec-VV essary to reverse the direction of rotation of the ratchet 2gear, this cannot be done while theA pawl isin contact with the teeth of the ratchet lgear; in my improved construction means are vprovided for disconnecting` the pawlA from the ratchet gear whenever itis desirable. rlhe preferred means shown in n the drawingsconsists of a foot lever 40 pivoted to theframe 1 at 4l, a chain or cord 42 drawn over guide rolls 43 and 44 connect ing with a lug on the pawl 2l. By this con struction a depression of the foot lever by the operative results in disconnecting the pawl and ratchet gear.

During the winding operation of a set 0f bobbins an intermittent motion exists in the members of my improved construction due tothe action of the pawl on the ratchet gear. ln order to eliminate part of this motion l provide a cut-out device for the winddown 7 shaft. Referringto Figs. 6 and 7 tl e winddown77 shaft 37 is slidably mounted in its bearings so that by pushing the shaft down suciently to disconnect the teeth of gear 36 from that of gear 33, rotation of the shaft 37 is stopped. A; stop collar 45 fastened to the shaft 37 and abutting against the bearirre` 39 limits the extent of f foot disconnects the pawl and the ratchetl gear and at the same time winds down the traverse rod by rotating;a the handle of the wind-down shaft. The necessary movements to perform this operation by the operative is done in a standing position with-` out any discomfort whatever thus being con duciveV to the contentment and good health of theV operative.

l claim: ln apparatus of the class described containing the following instrumentalities, viz :f

a plurality of spindles, a traverse member, yarn guiding means, installed thereon, a cam controlling the movements ofthe traverse member, a builder lever actuated by Vthe cam, bearings on the lever, take-up shaft supported in the bearings, means for imparting an intermittent rotary motion to said shaft, a chambered stud serving` as a fulcrum to the builder lever, an Aauxiliary shaft'rotatable in bearings formed in the chambered stud, connecting` gearing between the auxiliary shaft and take-up shaft, a .manually .f operated Awind-down shaft transmitting motion to the auxiliary shaft, means to maintain the wind-down shaft in or out of connection with the auxiliary shaft and lockingmeans for the same.

yln testimony whereof, l have signed this specification.
